T all whom, it may concern:

Be it known that I, UZZIEL P. SMITH, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Detachable Tires for Bicycles orother Vehicles, of which the following is a specification.

My invention relates to improvements in detachable tires for bicycles orother vehicles.

My invention has reference to improvementsinthatclass of tires known asclenchertires, and has for its object the provision of novel meansconnected with the outer sheath or casing of the tire for holding saidcasing upon the rim and for securing the inner airtube within thecasing.

A further object of the invention relates to the provision of novelmeans operatively conneeted with an adjustable retaining-band secured inone edge of the outer casing or sheath for adjusting said band andholding it in the adj usted position.

Other objects of the invention relate to certain details of constructionand operation of pirts, which will more clearly appear hereina ter.

I have illustrated my invention in the accompanying drawings, in Which-Figure 1 is a side elevation of a portion of a rim and tire, showingmyimproved adjusting means applied thereto. Fig. 2 is section on theline 2 2 of Fig. 1. Fig. 3 aview of the inside of a portion of an outersheath or casing, showing my improved retaining means applied thereto,said sheath or casing being Yiiattened or unrolled. Fig. 4 is a view ofthe inside of that portion of a rim having my adjusting means securedthereto, the view being arranged relative to Fig. 3. Fig. 5 is a sectionthrough the sheath or casing, taken on the line 5 5 of Fig. 3; and Fig.6 represents detached perspective views of my invention.

Referringto the drawings, the reference' numeral 1 indicatesthe rim of awheel, and 2 a tire secured thereon according to my invention. Saidtire, as usual, comprises an inner air-tube 3 and an outer casing orsheath 4. The numeral 5 indicates the iniiating-valve attached to theair-tube 3, said valve being of Athe ordinary or any preferredconstruction.

Secured along one edge of the casing 4 is an extensible wire ring 6,said Wire ring being retained in the casing by doubling the canvasthereof about said ring and then stitching the two thicknesses of canvastogether adjacent to the wire, as shown at 7 in Fig. 5. The wire ring 6is made eXtensible by having one end of the wire inserted and movable ina tubular socket 8, carried by the opposite end. Near the edge of thecasing is provided a circular opening 9, through which the valve 5 isdesigned to pass, and the wire ring 6 is bent laterally outward at thispoint, as indicated at 10, so that it will pass around the valve whenthe parts are assembled. Adjacent to the edge of the casing in which thering 6 is secured, but farther removed from said edge than the opening9, l provide two slits or elongated apertures 11 12, which are in linewith each other, the aperture 11 being longer than the aperture 12 for apurpose to be presently explained. In the opposite edge of the casing Isecure my improved retaining-band 13, which is formed of a flat metalband curved, arched, or otherwise bent upward throughout itslongitudinal center, as indicated at 14, to provide a continuous recessor seat 15 for the ring 6, as presently described, and having its sides16 17 adjacent to such arched portion 14 slightly curved upward, so thatthe band 13 will fit snugly and firmly in the concave of the rim. Isecure this band in the edge of the casing by doubling the canvasthereof about said band and stitching the two thicknesses of canvastogether adjacent to the band, as indicated at 1S in Fig. 5. casingcontaining the band 13 is also provided with an opening 19 for theair-valve 5 and with two elongated apertures 20 21, corresponding,respectively, with the apertures 11 12. Secured on one end ofthe band 13by rivets or otherwise is a metal clip 22, which conforms to theconfiguration of the band and at its outer end is provided with two arms23 24, formed integral with said clip and extending from opposite sidesthereof, said arms being curved to conform to the curvature of the rim.At their outer ends these arms are curved downward to form ears 25 26,in the inner edge of each of which is provided a recess or socket 27 28,respectively. The curved ends of the arms 23 24 are adapted to embraceopposite edges of the rim, as will presently The side of the" IOOappear. Secured ou the opposite end of the band 13 by rivets orotherwise is a metal clip 29, conforming in configuration to the band 13and projecting outward fromthe end thereof, said projecting portion 30being adapted to lie under the opposite end of the band 13 when thelatter is placed in position on the rim. The clip 29 is provided with anopening 31 for the passage therethrough of the valve 5, and the arch orcorrugation 14 extends in a curve about this opening, as indicated at32. lVhen the parts are in position on the rim, the curved portion 10 ofthe ring 6 will seat in or under the curved portion 32 of the clip 29.At its 1Inner end the clip 29 is provided with two arms 33 34', whichare integral with the clip and 'extend from opposite sides thereof, saidarms being curved upward to conform to the curvature of the rim. Attheir outer ends these arms are curved downward to provide ears 35 36,which are adapted to lit over opposite edges of the rim in the samemanner as the ears 25 26. Each of the ears 35 36 is likewise provided onits inner edge with a recess, said recesses being denoted, respectively,by the numerals 37 3S. Secured on the under side of the rim is a curvedplate 39, having an opening 40 for the passage therethrough of theair-valve. At opposite inner sides and near each end this plate isprovided with apertured lugs 41 42 43 44, which rest against the underside oi' the rim and hold the plate 39 out of contact therewith, andthrough the apertures in which lugs pass the screws 45, which secure theplate 39 to the rim. At one end on its under side said plate is providedwith a lug 46, havinga recess 47.

The numeral 4S indicates a slide-plate, which is fitted on the plate 39in a manner to permit it to be moved back and forth thereon. To this endsaid slide-plate is curved to conform to the curvature of the plate 39,and its ends are further bent or curved inward and downward, asindicated at 49, to embrace opposite edges of said plate and to form asliding contact therewith. Each of these curved ends is provided on itsouter side with a lug 50. On the bottom of the slide-plate 48 is anintegral lug 51, secured in which and projecting outward therefrom is ascrew-th readed bolt 52, on which is a thumb-nut 53.

Referring to Figs. 2 and 3, it will be seen that the arms 23 and 33project through the envelop inclosiug the band 13 and also through therespective apertures 2O and 21 in the cas- 1ng.

The parts are assembled as follows: The air-tube 3 is placed in thecasing, the valve 5 being inserted through the opening 19 therein andthe coincident aperture 31 in clip 29. The casing 4 is now made toinclose the tube, for this purpose the edge of the casing containing thering 6 being brought over and carried under the band 13, so that saidring lies immediately under the longitudinal recess or seat 15, formedby the arch or corrulthe rim the recesses 37 and 38 in the ears 35 and36 may be made to engage behind the respective lugs 43 and 44 on theinner side of the plate 39,while the recesses 27 and 28 in the ears 25and 26 are made to engage behind the lugs 50 on the slide-plate-48. rlhebolt 52, when said slide-plate is in position on plate 39, works in therecess 47, andthe nut 53 normally engages the lugr 46. By turning thisnut, therefore, the slide-plate 48 can be moved in a direction away fromthe lug 46, whereby through the engagement of lugs 50 with the ears ofclip 22 said clip, with the end ot' band 13 to which itis attached, maybe drawn inward 0r toward the opposite end of the band, and as the clip29 is held stationary by engagement of its ears with the lugs 43 44 itfollows that the band 13 will be drawn firmly about the rim, theposition of the parts when the tire is inated being shown in Fig. 2. Itwill be seen that the ring 6 will be held securely within the recess 15,and the broad bearingsurface afforded by the sides 16 17 of the band 13will operate to hold the tire firmly to its seat at both sides of therim. In the movement of the clip 22 the arms 23 and 24 will slide in theelongated apertures 11 and 2O of the casing, as will be understood. Toremove the tire, the uut 53 is turned so that the slide-plate 4S can bemoved toward the lug 46 to increase the circumference of band 13sufficiently to permit it to be passed over the edge of the rim.

It will be seen that my invention is simple and economical inconstruction and will permit of a tire being quickly attached to 0rremoved from a rim and that when on the rim the tire is firmly held toits seat at both sides.
